The 2000RPM figure is the level I'm comfortable with in my systems, which are equipped with the Zalman 7500. It's the level I'm comfortable with, noisewise.

Adjust the FanMate and see what fan level suits your taste.

The FanMate is optional but I keep it connected to all my Zalman heatsinks. Otherwise, they all run at full speed, which is terribly noisy. The BIOS will not be able to automatically adjust the Zalman's fan speed. With the FanMate, I just turn the knob until the fan hits an acceptable 2000RPM and leave it alone.
OK, please do not think I am being snide here.
Yet I ask, please, how do you know the RPMs?

Or is this just a rough estimate? And how does 2000RPM figure?

Is that just a convenient number you happen to like, or a recommendation by some authorative source for a sufficient fan speed to maintain good cooling in all conditions?

Thank you for a fine post and for any kind reply to my n00bish questions.
Best regards,
Ugly

It's not that, your fan is a PWM fan (pulse width modulation), look it up on wikipedia. Many new boards use PWM fans for the CPU so that the fan speed can be regulated by the board. It's a good, quiet, dependable way to regulate fan speed.
I am a n00b. And I apologize. Yet I do not understand.
Yes, the idea that one can control power by changing the duration of the full-ON pulse (PWM) makes perfect sense.

• But the FanMate, is that optional or not, please?

If, as you say, the mobo may control the fan; then why would I presume to interfere via the knob?
Sounds redundant to me!

Honestly, if it works just as well in cooling without FanMate2, what's the point of continuous adjustment via a knob?

What's the (missing) forth pin-hole for, please? Was it intended for a RPM sensor perhaps?
(the photo is from mobo manual. the actual is missing where I have blacked out)

Thanks, Ugly
